CVE-2026-46089

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> zram: do not forget to endio for partial discard requests<br /> <br /> As reported by Qu Wenruo and Avinesh Kumar, the following<br /> <br /> getconf PAGESIZE<br /> 65536<br /> blkdiscard -p 4k /dev/zram0<br /> <br /> takes literally forever to complete. zram doesn&amp;#39;t support partial<br /> discards and just returns immediately w/o doing any discard work in such<br /> cases. The problem is that we forget to endio on our way out, so<br /> blkdiscard sleeps forever in submit_bio_wait(). Fix this by jumping to<br /> end_bio label, which does bio_endio().
